. IMPROVEMENT IN GAS-BURNERS.

Specification forming part of Letters Patent No. 112,637, dated March 14, 1871.

.To all whom itmay concern:

Beit known thatl, MARK ROsENwAX, of New York city, in the county and State of New York, have invented a new and useful Improvement in Gas-Burners; and I do hereby declare that the following is a full, clear, and f exact description thereof, which will enable after `it enters the stem of the burner, and conducting itin two currents into ends of a tubular arch, the crown or upper side of which arch is slit for the discharge of the gas, and becomes the point of ignition, as will be hered inafter more fully described.

In the accompanying drawing, Figure l represents a central vertical section of my improved gas-burner. Fig. 2 is an edge view.

Similar letters of reference indicate correspending parts. i

A is the burner with a stem,]3, which screws onto the gas-pipe in the ordinary manner. C C are tubes branching from B, at the pointD inopposite directions, and connecting with the ends of the tubular arch E. F represents a narrow slit in the crown Or upper side of this arch, through which the gas escapes, and which circular line between. the points Gr G forms the base of the iiame when the gas is ignited.

The gas being discharged through the extremely fine slit or crack F is in so thin a sheet or current that nonegcan escape nnburned, while the iiame is so lnuch expanded in consequence that the illuminating power of a givenquantityof gasis greatly increased, the result being a very material saving to the consumer.

The burner may be strengthened by the cross-bar H and side braces I I, or ornalnen ted in any manner to suit the taste.

Having thus described my inventiOn,`I claim as new and desire to secure by Letters Patent- "The gasburner A, constructed to operate substantially as shown and described.

The above specification of my invention signed by me this 10th day January, 1870.

MARK ROSENWAX.
